ZF 0730.514.793 SNAP RING for WG90 | OEM Genuine Part

Overview

The ZF 0730.514.793 SNAP RING is a critical retention component engineered for the WG90 and WG94 series transmissions. This OEM genuine part secures internal assemblies—such as bearing packs and gear clusters—within the main transmission housing, preventing axial movement under high torque loads. The SKU 0730.514.793 is specifically designed to fit into precision-machined grooves, ensuring a positive lock that maintains gear alignment and shaft stability. When installed correctly, this snap ring works in concert with the TRANSMISSION HOUSING to contain hydraulic pressure and mechanical forces during operation.

Symptoms of Failure

• Transmission oil leaks near the housing joint: A worn or fatigued snap ring can allow the HOUSING to shift slightly, breaking the seal and causing fluid seepage.
• Intermittent gear slipping under load: When the snap ring loses its tension, internal components can drift out of position, leading to incomplete gear engagement and power loss.
• Unusual metallic rattling or vibration: A loose snap ring permits axial play in the shaft assembly, generating noise and vibration that worsens with RPM changes.
• Hard shifting or delayed engagement: Misalignment caused by a failing snap ring can disrupt the TUBE alignment, affecting hydraulic circuit timing.

Technical Specifications

Compatibility

This snap ring is a direct fit for the ZF WG90 and WG94 series transmissions. It is also commonly used in the following models: WG180, WG200, WG210, and WG250. The part interfaces directly with the CYLINDRICAL PIN that indexes the snap ring groove, ensuring rotational alignment. Always verify the groove dimensions in your specific housing variant before installation.
